Product details
Overview
R5F101FFDFP#V0 from Renesas is a 44-pin LQFP-44, 32-bit RL78/G13 microcontroller with 96 KB flash, 4 KB data flash, 4 KB RAM, and no on-chip data flash programming capability (G-series variant). It operates from 1.6–5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT for battery-powered industrial sensors and metering systems.
For engineers reviewing the R5F101FFDFP#V0 datasheet, R5F101FFDFP#V0 pinout, R5F101FFDFP#V0 application, or R5F101FFDFP#V0 equivalent, key selection criteria include its 44-pin LQFP package, absence of data flash (vs. F-series), 10-bit ADC with 26 channels, RTC + LVD + DMA support, and industrial-grade temperature range (−40°C to +85°C).
Technical Context
The R5F101FFDFP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates a 16-bit timer array (16 channels), real-time clock with calendar/alarm, and 10-bit A/D converter with internal reference voltage (1.45 V) and temperature sensor.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8 CSI/SPI channels, and DMA controller (4 channels) enabling background data flash rewriting while executing code - though this unit lacks data flash memory per G-series designation.

FAQ
What is the flash memory configuration of the R5F101FFDFP#V0?
The R5F101FFDFP#V0 contains 96 KB of on-chip code flash memory and 4 KB of RAM. It does not include data flash memory, as indicated by the 'G' in its part number (per Renesas RL78/G13 documentation: '101' = no data flash, '100' = with data flash). This makes it suitable for applications where parameter storage is handled externally or via code flash wear-leveling techniques.
Does the R5F101FFDFP#V0 support real-time clock functionality?
Yes, the R5F101FFDFP#V0 integrates a hardware real-time clock (RTC) with full calendar support (year/month/day/hour/minute/second), alarm function, and clock correction capability. It operates independently in STOP mode using the 32.768 kHz subsystem clock, enabling timekeeping during ultra-low-power operation without CPU intervention.
What is the operating temperature range for the R5F101FFDFP#V0?
The R5F101FFDFP#V0 is rated for industrial operation from −40°C to +85°C, as confirmed by the 'D' suffix in its ordering code (R5F101FFDFP#V0 → 'D' = Industrial grade). This qualifies it for deployment in harsh environments such as factory floors, outdoor meters, and HVAC systems without derating.
Can the R5F101FFDFP#V0 perform analog-to-digital conversion?
Yes, the R5F101FFDFP#V0 features a 10-bit successive-approximation A/D converter with up to 26 input channels. It includes an internal 1.45 V reference voltage and an integrated temperature sensor - both accessible via dedicated pins (P20/P21 and ANIxx) - enabling accurate ratiometric measurements and thermal monitoring without external components.
Is the R5F101FFDFP#V0 pin-compatible with other RL78/G13 variants in 44-pin LQFP?
Yes, the R5F101FFDFP#V0 shares identical pinout and package (44-pin LQFP, 0.8-mm pitch) with all other RL78/G13 devices in the same pin-count group, including R5F100FFDFP#V0 and R5F101FGDFP#V0. This allows direct PCB reuse when upgrading flash size or adding data flash, provided peripheral usage aligns with the target variant's feature set.
